The dinner is scheduled for Sunday, April 28, at the new Cobo Conference Center in downtown Detroit.

Pelosi, a California Democrat who was the first woman to serve as speaker of the House, visited Cobo in 2010 to tour the Detroit Auto Show.

"Representative Pelosi is anxious and excited about coming to the city of Detroit at this very critical time in our history," the NAACP said in a press release. "She will speak to issues from a national point of view that have a lasting impact on those of us who live in the city of Detroit."

Attorney General Eric Holder served as keynote speaker at last year's Freedom Fund Dinner, which draws an estimated 10,000 attendees and is billed as the largest sit-down dinner in the country. Other recent speakers included U.S. Reps. John Lewis and James Clyburn.
